Eye dilation typically lasts between 4 to 24 hours after the administration of dilating eye drops. The exact duration depends on several factors including eye color, age, the type and strength of the drops used, and individual differences in eye response. For most people, the effects—such as enlarged pupils, blurry vision, and light sensitivity—tend to wear off within 4 to 6 hours, but in some cases, especially for those with lighter-colored eyes or children, dilation can persist up to 24 hours or even longer
. During this period, vision may be blurry and the eyes can be very sensitive to light, so wearing sunglasses and avoiding driving or activities requiring clear vision is recommended until the effects subside
. If dilation effects last beyond 24 hours or cause discomfort, consulting an eye care professional is advised
. In summary:
- Typical duration: 4 to 24 hours
- Average for most adults: 4 to 6 hours
- Longer duration in children and people with lighter-colored eyes
- Side effects include blurry vision, light sensitivity, and difficulty focusing on close objects
- Protective measures: wear sunglasses, avoid driving until vision clears
This variability means there is no exact rule for how long dilation lasts, and individual experiences can differ significantly
